Abstract
Test device for detection and visual indication of a specific analyte in a liquid sample such as a body fluid. The device includes a biodegradable housing, a test strip and a lid. The device is configured for placement in concentrate or dilute test liquid that is for example contained in a vessel. One end of the test strip wicks the liquid being tested into the housing and across a control site and test site which provide visual indication that the device is working correctly and whether the analyte being tested is present in the test liquid. An antibody specific to the antigen being tested may be provided on the test strip. The test device for example detects specific antigens in dilute urine, such that the device may be placed in a toilet bowl after urination.
Claims21
A test device comprising:
- a bowl-shaped housing with a peripheral rim;
- a plateau extending from an inner, bottom surface of the housing and having a recessed area for supporting a test strip within the housing;
- the test strip comprising a reagent for reacting to a preselected analyte;
- a lid for fastening to the peripheral rim, to cover the bowl;
- an opening through the housing adjacent a first end of the test strip;
- a wicking device extending through the opening and connected to the first end of the test strip;
- and
- a view port in the lid, overlying and aligned with the test strip;
- wherein a test liquid contacting the test strip exposes the reagent to the analyte, when the test device is placed in the test liquid, the wicking device engaging the liquid and wicking the liquid through the opening and onto the test strip;
- the plateau elevates the test strip above the test liquid to eliminate the possibility of the test strip absorbing the liquid directly through the housing.
A testing device for determining the presence of an analyte in liquid, comprising:
- a housing having a bowl section, a rim extending from the periphery of the bowl section;
- a plateau oriented through the bowl section for supporting a test strip, the test strip including a reagent for reacting to the analyte;
- a lid for fastening to the rim to cover the bowl section;
- an opening through the housing adjacent a first end of the test strip;
- the first end of the test strip extending through the opening, the first end of the test strip being bent generally downward and wrapped around the housing, the first end secured near an outer bottom surface of the housing;
- and
- a view port in the lid and aligned with the test strip;
- wherein the test device floats and self-rights to display the view port to a user when placed in a vessel of test liquid and the first end of the test strip wicks the test liquid onto the test strip to expose the reagent to the test liquid;
- the plateau elevates the test strip above the test liquid to eliminate the possibility of the test strip absorbing the liquid directly through the housing.
